Lefébre Rademan
Lefébre Rademan, new captain of the Free State Crinums netball team, could be one of the star players in the Premier League. She is a fifth-year Education student.

The Free State Crinums netball team, a de facto Kovsie team with all 15 squad members enrolled for courses at the University of the Free State (UFS), will draw inspiration from their success in last year’s Varsity netball tournament. The Kovsies won the student competition for a record third time. 

During the weekend of 10 May 2019, the Crinums will play their first match in the 2019 Premier League. They lost a couple of key players in captain Alicia Puren, Protea Khanyisa Chawane, (both playing for the national invitational team in the league), Khomotso Mamburu (moved to Cape Town), and Meagan Roux (injured). They do, however, still have the services of players such as Tanya von Berg (playing in her sixth Premier League, one of only a handful of players to do so), Lefébre Rademan, Sikholiwe Mdletshe, Ané Retief, Gertriana Retief, and Rieze Straeuli. Rademan is the new captain and was one of the standout players in last year’s Varsity netball, earning three Player of the Match awards, including the Player of the Final. 

The team will again be coached by Burta de Kock, who is also the head coach of the Kovsies. Under her leadership, the Crinums won the Premier League for the first three years (2014 to 2016). Last year, the Crinums ended fourth. De Kock will be assisted by Martha Mosoahle-Samm. She is a former Protea assistant coach who also captained South Africa and played for the UFS between 1997 and 1999.

There are four first-year students in the squad of 15 players: Oageng Khasake (wing attack), Ancia Pienaar (goalkeeper), Rolene Streutker (goal shooter), Boitumelo Mahloko (goal defence). Pienaar and Mahloko both represented South Africa at junior level in 2018.

■ Crinums squad: Ané Retief, Gertriana Retief, Jana Scholtz, Lefébre Rademan, Sikholiwe Mdletshe, Tanya von Berg, Rieze Straeuli, Claudia van den Berg, Zandré Smit, Oageng Khasake, Bianca de Wee, Ancia Pienaar, Rolene Streutker, Chanel Vrey, Boitumelo Mahloko.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
